Firefly Blade: Credit Card Knife for Your Wallet
Compact, Reusable Wallet Knife Card with Built-In Firestarter
The Firefly Card Blade is a credit card size wallet knife made from 1095 high carbon blued spring steel. It carries flat like a wallet knife card but gives you real cutting power thanks to its chisel ground edge and thicker build. It fits in a wallet, pocket kit, or Altoids tin, making it one of the easiest ways to carry a reliable knife for wallet storage. The silicone handle holds a hidden ferrocerium bar, giving you a blade and fire starter in one compact tool. Twice the thickness of our standard card tools, the Firefly is built for real cutting, carving, scraping, and fire work, not for show.
Why the Firefly Wallet Knife Exists
The Firefly Blade Credit Card Knife was built for people who want a real knife that is always with them, not left at home or buried in a pack. Most knives are too big or too heavy for everyday carry, but your wallet is always with you. That is why we created a true knife for wallet carry that stays flat and ready without adding bulk.
When you cannot carry a full size blade, the Firefly gives you dependable cutting power in a slim wallet knife card design. It handles everyday jobs like trimming rope, opening packages, and cutting cord, but it is also strong enough for carving kindling or prepping fire materials. It is the sharp edge that is always there when you need it and invisible when you do not.
The hidden ferro rod brings even more capability to your kit. Your wallet knife does more than cut. It can help you start a fire in the field, giving you two of the most important survival tools in one compact piece of gear.
At Grim Workshop, we believe in putting a backpack’s worth of tools in your wallet. The Firefly Blade was built around that idea. It is compact, reusable, and designed for real life, not just for show.
Firefly Card Blade: Built for Real Life
The Firefly Blade Credit Card Knife isn’t just a backup—it’s a working tool made to perform. Each blade is Made in the USA, field-tested, and designed for repeated use. The blued steel finish prevents rust, while the reusable flat design makes it easy to carry anywhere.
Whether you’re lighting a fire, cutting paracord, or slicing food at camp, the Firefly Blade is compact enough for your wallet yet capable enough to rely on when it matters most.

Firefly Wallet Knife Card: Built To Last
Every Grim card tool is made from long lasting materials and produced in small batches so quality always comes first. The Firefly is no different. This wallet knife is made from 1095 high carbon steel, a tough spring steel that can last a lifetime with simple care. High carbon steel is extremely strong, but it is also sensitive to moisture, so a light coat of oil now and then keeps your wallet knife card ready for years of use. Upon arrival give it a light coat of oil and it's ready to go!
The Firefly is backed by the Grim Guarantee, so if your knife for wallet carry ever fails during normal use, we refund, replace, or exchange it. Designed in Texas and made in the USA, this tool is built to outlast the problem. When you depend on your gear, reliability is not optional.
